Makeover Lemon Streusel Muffins

• 1/4 cup butter, softened
• 3/4 cup sugar
• 2 large egg yolks, room temperature
• 1 teaspoon grated lemon zest
• 1 cup cake flour
• 1 cup all-purpose flour
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 1/4 teaspoon baking soda
• 1/2 cup lemon juice
• 1/2 cup lemon yogurt
• 4 large egg whites, room temperature
• 2 tablespoons all-purpose flour
• 2 tablespoons brown sugar
• 1/4 teaspoon ground nutmeg
• 1 tablespoon cold butter
• 1/4 cup chopped walnuts

1. Preheat oven to 375u0b0. In a large bowl, beat butter and sugar until crumbly. Beat in egg yolks and lemon zest. Combine the flours, baking powder, salt and baking soda; add to the butter mixture alternately with lemon juice and yogurt.
2. In a small bowl with clean beaters, beat egg whites until stiff peaks form. Fold into batter. Coat muffin cups with cooking spray or use paper liners; fill two-thirds full with batter.
3. For streusel, combine the flour, brown sugar and nutmeg; cut in butter until crumbly. Stir in walnuts. Sprinkle over muffins. Bake until a toothpick comes out clean, 15-20 minutes. Cool for 5 minutes before removing from pan to a wire rack.
